They are the same size. BIG
flat top two wheels in back none in front accept ropes flat top two wheels in back none in front accept ropes
its to do with gearing think about having small wheels on the back they.d never push the big wheels

They are called as bigfoot cars
as fast or slow as you want, it depends on the gearing, big front sprocket w/ little back sprocket = speed, small front big rear = torque but with a 14/42 you might reach 75-80 w/ wind at your back
typically you want a a smaller sprocket in back and bigger one in front.. bigger one in back with stock in front will cause quicker acceleration small on back and big in front will cause you more speed but if you put a smaller one in back put a bigger one in front
big wheels because they are good for handling
Have bigger wheels and a more powerful mouse-trap, like the really big ones that are a foot long and half a foot wide.
The front wheel(s) are only for steering and holding the front end up. The back wheels supply the power and must have traction. Making them big lets them carry big tires which keeps the tractor from getting stuck in muddy fields and keeps them from slipping so easily. The big lugs on the tires also help in that regard.
No front brake calipers are to big. If you must calipers can be machined down at a big cost.
Big wheels of course. They will protect you better from falls over potholes
